Curved top boxes

Finally finished something for my first post here. These are curved top boxes that could be used for jewelry, candy, or whatever. The box on the right was a test piece that I made out of 2X4’s re-sawn to 3/8” thick; overall it is 10” X 5” X 4”. The top was milled on a router jig from a 2X6 and has a radius of curvature of about 12.5” and is about 3/8” thick. The dovetails were cut on a router table using a dovetail jig that I designed for small boxes and trays using a straight ¼” cutter for the pins, and 5/16” 8 deg. dovetail bit for the tails. Was looking for a sort of minimalist look, so no hinges, just a ¼” ball bearing set in counter-sinks at the back edge of the top and the box sides – barely visible in one of the pics (won’t do that again). The other box on the left was made from birch milled from some large branches trimmed from a backyard tree. Same approach as with the other box, but radius of curvature of the top is about 6”, and I used 1/8” brass pins for the hinges. Overall dimensions are 8 ¾ X 5 ¾ X 4”
